    Biggest Virus Yet Found, May Be Fourth Domain of Life?

    Scientists have found the biggest viruses known, and these pandoraviruses have opened up entirely new questions in science—even suggesting a fourth domain of life, a new study says.

    Each about one micron—a thousandth of a millimeter—in length, the newfound genus Pandoravirus dwarfs other viruses, which range in size from about 50 nanometers up to 100 nanometers. A genus is a taxonomic ranking between species and family.

    In addition to being huge, pandoraviruses have supersize DNA: 2,500 genes as compared with 10 genes in many viruses. (Get a genetics overview.)

    Microbiology was similarly upturned about ten years ago when scientists found the genus Mimivirus—the first large virus of its kind at about 0.7 micron.
